Methylation is a form of alkylation, i.e. the transfer of an alkyl group to another molecule . Methylation is specifically the addition or substition of a methyl group to a molecule. Methyl groups are alkyls made from methane and are carbon atoms attached to 3 hydrogen atoms -CH3 . It can be involved in the expression of genes, as well as protein function regulation and the metabolism of RNA.
